New Computational Theory Could Take Transmutation a Step Forward

Right from the Middle Ages, alchemists have sought to transmute elements. A well-known example of this is the long pursuit of turning lead into gold. In the modern era, transmutation has been achieved, however, on a minute scale with the aid of an enormous particle accelerator.

New Laser Technology Creates Color 3D Images in Liquid

Researchers have developed a completely new type of display that creates 3D images by using a laser to form tiny bubbles inside a liquid “screen.” Instead of rendering a 3D scene on a flat surface, the display itself is three-dimensional, a property known as volumetric.
